Thank you for re-supplying your thread once again. I am interested in only cutting out the inside portion of the upper basket on my oil bath air filter and getting a correctly fitting dry filter to install inside of the upper canister. When the dry filter (inside the upper canister)and the upper canister are installed into the lower part, or bowl if you will, you will not see the dry filter and the look is very close to that of the original.

This is why I am trying to determine the correct filter dimensions, manufacturer and part number before 'chopping' up the top portion of my filter.
